Washington Supreme Court Chief Justice Mary Fairhurst, right, and Associate Chief Justice Charles Johnson, left, listen Thursday, May 17, 2018, as Paul Lawrence, center, an attorney representing teachers unions and other groups who have sued over Washington state's 2016 charter school law, presents an argument in Olympia, Wash. The lawsuit argues that using public money to operate alternative, nonprofit charter schools over which voters have no control is forbidden by the state Constitution and diverts money from already underfunded public schools.
